AuthorTopic: 30 inch brushless hydroplane project (Read 11469 times)

Fast electric has a very steep and unforgiving learning curve. F1 madness has pointed out that the 4mm flex cable will fail under the torque of the motor, unfortunatly for me thats the same propshaft thats installed in my boat. I use a 40mm 1.4 pitch graupner propeller diven by a 2000kv 3754 outrunner on 4s. The first two outings ive had were succesful but a bit too slow so im upping to 5s, the batteries havent arrived yet i just hope it all holds out. touch wood

id use 5s or even 6s but that motor will only handle 4s so stuck with them but i dont think thats a bad thing really i only got my first rc boat 4 weeks ago so a boat on 6s might be a bit too far yet lol

alot of what ive done so far is pure guess work having never done any of this before the whole project minus the batterys has only cost me £130 which i thinks pretty good i know i could of bought something better for the money but half the fun was building it and working things out ive really enjoyed it

my shaft has held ok so far so for now ill stick with it unless it fails. Hope not (touch wood). I would have thought that your motor should be able to withstand 5 or 6s. have you got a link to where you got it?

You will need a method of recovery for your boat by they way.

got a way of getting the boat back i was planning on pushing it back with one of my others lol
